RATCHET IMPLEMENT.

Specification of Letters Patent.

Patented Dec. 1 1, 1 9C 6.

Application filed April 17. 1906. Serial No. 312,275.

To all whom it may concern:

Be it known that I, CLARENCE H. BILL" INGS, a citizen of the UnitedStates, residing at Jacksonville, in the county of Duval and State ofFlorida, have invented a new and useful Ratchet Implement, of which thefollowing is a specification.

This invention relates to ratchet implementssuch drivers, boringimplements, and the like-and has for its object to improve theconstruction and increase the efficiency of devices of this character.

IVith these and other objects in view, which will appear as the natureof the invention is better understood, the invention consists in certainnovel features of construction, as hereinafter fully described andclaimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are. denoted by like designatmg characters,is illustrated the preferred form of the embodiment of the inventioncapable of carrying the same into practical operatlon.

In the drawings, Figure 1 is a side elevation of the improved implementapplied to a screw-driver. Fig. 2 is a section on the line 2 2 ofFig. 1. Fig. 3 is a side elevation, partly in section, of the improvedimplement applied to a drill-stock or like implement. Figs. 4 and 5 areviews of two of the attachments which may be alternately employed withthe structure shown in Fig. 3. Fig. 6 is a side view of a socket adaptedto be em ployed with the structure shown in Fig. 3. Fig. 7 representsthe different parts of the operating-handle in perspective anddisconnected.

The improved implement herein described may be readily applied toscrew-drivers, drill-stocks, boring implements, and the like and for thepurpose of illustration is shown in Figs. 1 and 2 applied to ascrew-driver and in Fig. 3 applied to a conventional stock for a drillor boring implement.

In the improvement is embraced a toothed disk or enlargement 10, appliedto the stock of the implement. In Fig. 1 the toothed member is shownattached to the stock 11 of an ordinary screw-driver, and in Fig. 3 thetoothed member is shown applied to a conventional stock 12 of aconventional boring or drilling implement. The member 10 may be formedintegral with the stock with which improvements in as drills,screwsocket-wrenches,

tached thereto in any suitable manner and is preferably formed withspaced teeth of uniform size and shape upon both sides, so that theimplement may be rotated in any direction, as hereinafter shown. Theimproved device also embraces a detachable handle adapted to be disposedupon the stock and provided with a pawl adapted to engage the teeth ofthe member 10, and thus enable the stock to be forcibly rotatedintermittently. The operating-handle is provided with open recessesadapted to fit over the stock at the opposite sides of the member 10, asshown, with the tooth-engaging pawl between the recesses.

The operating-handle is preferably con structed of spaced cheek-plates13 14, sepa rated by a spacer member 15, the cheekplate 13 having anopen recess 16 and the cheek-plate 14 having an open recess 17, thespacer member 15 equaling in thickness the thickness of the member 10,so that when the three parts 13, 14, and 15 are united by rivets 18 orother suitable fastenings the recesses 16 17 may be engaged with thestock of the implement at each side of the member 10. The spacer member15 is provided with an integral resilient pawl 19, adapted to engage theteeth of the member 10 when the connected cheek-plates 13 14 aredisposed upon the stock, as above described. By this arrangement it willbe obvious that when the handle is disposed upon the stock, as abovenoted, with the resilient pawl bearing against one of the teeth an d thehandle moved in one direction the pawl will pick up the member 10 andthe stock to which it is attached and rotate it, and at the returnstroke the resilient pawl will simply click over the teeth of the member10 and not produce any eflect thereon. By this simple means a veryeflicient ratchet implement is produced which may be inexpensivelymanufactured and employed in connection with a variety of implements.

The structure shown in Fig. 3 is provided at one end with a threadedrecess 20, in which a handle 21 may be inserted or in which anadjusting-screw 22 may be inserted, as required, while the other end ofthe member 12 is provided with a socket 23, adapted to receive drill,boring-tool, or other similar implement or to receive the stem of asocket-wrench 24. (Represented in Fig. 6.) The handle portion of thedevice being detachable and the toothed member 10 having its teeth alikeon both sides, the handle member may be readily reversed in positionupon the stock, and thus rotate the stock in either direction. Theterminals of the hooks of the handle members are preferably inclinedoutwardly, as shown, to facilitate the placing of the implement upon thestock, as the outwardly-inclined terminals of the hooks prevent thelatter from catching upon the toothed member.

Having thus described the invention, what is claimed as new is- Thecombination with a stock having disk provided with spaced peripheralteeth and extending laterally thereof, of an operating-handle comprisingspaced plates hav ing transverse recesses at their free ends with theterminals of the portions of the plates exteriorly of the recessescurving outwardly in opposite directions to facilitate the engagementwith the stock, and a spacer disposed between said plates and providedwith an integral resilient pawl for yieldably engaging the teeth of saiddisk, said pawl being disposed at the closed ends of the transverserecesses in said spaced plates, and means for connecting said plates andspacer member.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two witnesses.
